所谓专业,就是将整合的功能重新拆分,每部分都由专门的设备负责。对于大部分车而言,车载音响就是一台主机和几个扬声器,自然也不会有什么好声音。X5的原车音响稍微好一点,采用宝马三个级别(Stereo、Hifi、Top-Hifi)原车音响中的第二级别,比最低级的系统多了个功放。主机采用平衡输出至功放,而功放则自带分频输出,将信号分别传输至高中低音扬声器。这样一套系统的优点是三频均衡,有不错的空间感,但对于追求更高音质享受的音响玩家而言,原车扬声器和功放的水准都较差,整体音色显得较单薄,缺乏韵味。
The so-called professional, is to re-split the functions of integration, each part is responsible for the specialized equipment. For most cars, car audio is a host and several speakers, and naturally no good sound. The X5’s original car sound a little better, with the second level in the original stereo of the BMW three-level (Stereo, Hifi, Top-Hifi), more than a power amplifier of the lowest level system. The host uses a balanced output to the amplifier, while the amplifier comes with sub-frequency output, the signal is transmitted to the high school bass speaker. Such a system has the advantage of tri-band equalization, there is a good sense of space, but for the pursuit of higher sound quality audio players, the original car speakers and amplifiers are poor standards, the overall tone is relatively thin, the lack of charm.
